HALF PULSE [4 records]

Record 1 2014-01-29

English

Subject field(s)
  • Atomic Physics
DEF

A molecular device capable of converting energy into movement and able to generate forces on the order of piconewtons.

CONT

The nanomotor has a positioning stroke up to some centimeters while operating with atomic resolution and thus builds a bridge over eight orders of magnitude. The nanomotor is a piezo driven linear motor consisting of a cylindrical housing and a slider with a free axial hole inside. It utilizes a piezo tube for fine positioning and a pulse wave produced by the same piezo tube for coarse movements. Every point of its stroke can be reached with a speed of up to 5 mm/s. In its free axial hole the nanomotor can transport a tip, a hose, an electrode, a hypodermic needle, a glass fiber or even a microgripper. The nanomotor is available in three different versions. The "small" nanomotor is half the size of a match stick. It can lift six times of its own mass. The dynamic force of this nanomotor is so high, that even imprints in diamond surfaces can be produced. Special versions of the nanomotor can operate in ultra high vacuum, in liquid helium, even under water or as non-magnetic drives.

PHR

Primer, virus nanomotor.

PHR

Nanotube nanomotor.

Key term(s)
  • nano-motor

French

Domaine(s)
  • Physique atomique
DEF

Assemblage de molécules comportant des éléments de dimensions nanométriques qui, lorsqu'ils sont alimentés par une source d'énergie, répètent incessamment le même mouvement.

PHR

Nanomoteur biologique, protéique.

Key term(s)
  • nano-moteur

Spanish

Campo(s) temático(s)
  • Física atómica
CONT

El nanomotor es capaz de desplazar cargas y de girar como un motor convencional, pero un millón de veces más pequeño que el agujero de una aguja. La investigación abre las puertas a la creación de nuevos dispositivos nanométricos capaces de llevar a cabo tareas mecánicas con futuras aplicaciones en ámbitos como la biomedicina o los nuevos materiales.

Record 2 2002-03-28

English

Subject field(s)
  • Remote Sensing
CONT

"Range resolution" refers to the ability to resolve different objects in the range direction. This requires that the objects be separated by more than half the pulse length. [If two] objects... cannot be resolved, [they] will be seen as one object [and if two other objects] can be resolved, [they] will appear as two objects.

OBS

range direction: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

French

Domaine(s)
  • Télédétection
DEF

Écart minimal, en distance-temps, que peut déceler un capteur actif en hyperfréquence.

OBS

résolution en portée : terme uniformisé par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).

English

Subject field(s)
  • Lasers and Masers
DEF

The time during which the laser output pulse power remains continuously above half its maximum value.

OBS

laser pulse duration: term and definition standardized by NATO.

French

Domaine(s)
  • Masers et lasers
DEF

(Intervalle de) temps pendant lequel l'impulsion de puissance émise par le laser a en permanence une valeur supérieure à la moitié de sa valeur maximale.

OBS

durée d'impulsion laser : terme et définition normalisés par l'OTAN.

Spanish

Campo(s) temático(s)
  • Láser y máser
DEF

Tiempo durante el cual el impulso de salida del láser es mayor que la mitad de su valor máximo.

Record 4 2000-08-09

English

Subject field(s)
  • Processing of Mineral Products
  • Mining Equipment and Tools
  • Mineral Processing (Metallurgy)
CONT

The two main types used in industry are "moving-screen" and "fixed-screen" jigs. In the former the screen box is moved upward and downward in a tank of water. In the latter, the screen box is stationary and the jigging fluid is pulsed upward and downward through it. Water is normally the pulsing fluid.... Fixed-screen Jigs. The oldest type of jig in use is the Harz [in which] an ore box... occupies about half the plan area of a compartment in a water-filled tank, called the "hutch". In the other half of this compartment a loosely fitting plunger moves vertically, so as to pulse water upward and downward.

French

Domaine(s)
  • Préparation des produits miniers
  • Outillage et équipement (Exploitation minière)
  • Minéralurgie (Métallurgie)
CONT

Les principaux types utilisés dans l'industrie sont les jigs à cribles fixes et les jigs à cribles mobiles. Pour les premiers, la pulsion du liquide est assurée, généralement, par un diaphragme ou un piston. [...] Le type le plus ancien est le jig Harz [qui] est constitué par une huche divisée en deux compartiments: l'un est muni d'un piston plongeur, l'autre d'une grille [...]

OBS

L'ancêtre des jigs à grille fixe est le jig Harz dont la pulsation était créée par un piston d'où le nom de bac à piston ou à pistonnage que l'on peut rencontrer dans les articles anciens. Les concentrés étaient prélevés dans la huche par vanne et contre-vanne.
